Mix the buckwheat and plain flours together in a mixing bowl.
Add the beaten egg, then the water and milk.
Whisk to a smooth batter. It should be the consistency of runny/heavy cream - if it isn't, add 1-2 tablespoons of water.
Cover and leave in fridge for an hour, or overnight. If it thickens in the fridge, add a tablespoon more water to thin slightly back to the consistency of cream.
To make the crepes:
Heat a non stick frying pan over a medium heat add add a teaspoon of oil.
Spoon 2 tablespoon batter into the pan, swirling it slightly. Fry for a couple of minutes, until the top is mostly set, then flip over.
As soon as you flip the crepe over, sprinkle with some ham, then a little spinach and then some cheese. Leave 30 seconds or so, then fold two opposite edges over to meet in the middle. Press them slightly with the spatula to make them stay.
Cook for another minute, or until the cheese is melted and the bottom of the crepe is golden, then remove to a plate and cover to keep warm whilst you make the rest of the crepes.
Repeat the steps, until all the batter and filling has been used.
Eat the crepes straight away.
Notes
Estimated costs: Australia $6.46. Per serve = $1.62UK £3.92. Per serve = £0.98pAmerica - I am yet to calculate the estimated ingredients costs to make this recipe in the US. If you would find it useful please contact me and I'll get calculating :) Buckwheat Flour - buckwheat flour has quite a strong taste, therefor to make these crepes ore toddler friendly I have mixed it with plain wheat flour. It adds a lovely savoury flavour to the crepes and is slightly nutty. BlinisHam - any good sliced ham works well. Or you could use leftover cooked ham or gammon, finely shreddedCheese - I use a basic cheddar cheese, but you could use gruyere cheese or a vintage cheddar.Other Toppings: sliced fried mushrooms, a fried egg, smoked salmon, brie, goats cheese...buckwheat pancakes are such a great base for a variety of fillings!
